Note on Main Board Replacement
Take the following setting when the main board is replaced.
- Shipment data setting (Color Shading Correction, Gamma Shipment)

Adjustment Ship data Setting
This projector stores "Color Shading Correction Data" and "Gamma Data" in the flash memory (IC801) and memory
(IC1387) on the main board. Those shipping data have been setup according to the optical characteristics of the
mounted LCD panels preciously in the factory. When replacing the main board, you need to read out the those setting
data stored in the memory ICs on the previous main board and write down them into the memory ICs on the new main
board. By this way, the projector enables to reproduce the picture which has properly adjusted color shading correc-
tion, gamma correction. If it is not possible to read out the data, or replace the LCD/Prism assy, you need to write the
initial data which is setting the typical characteristics of the LCD panel into the memory ICs on the new board. For
further details, refer to the operation manual of the software [PROJECTOR SERVICE TOOL v4.0].
Serial No. Setting
Each projector has an unique serial no. controlled in the factory. There are ways to check this serial no. The
one is printed on the rating label on the cabinet, the other one is displayed on the "Information" on the on-screen
menu. The serial no. displayed on the on-screen menu is stored in the memory IC (IC1387) on the main board.
When replacing the main board or memory IC, you need to write the serial no. referring to the serial no. printed
on the rating label with the serial no. setting tool. For further details, refer to the operation manual of the serial no.
